Java 使用正则表达式从邮件中提取潜在客户信息

我正在开发一个邮件检索器，只用于检索一些需要的邮件，并使用regex从这些邮件中进一步提取细节。 我必须从以下邮件中提取姓名、要求等详细信息。如何使用正则表达式？？请帮我做这个。提前谢谢

Lead Details 
Caller Name: Mr Rahul from Rajouri Garden 
Caller Requirement: Money Exchangers 
Caller Phone: +918459761134 
Caller Email: rchand.rahul@gmail.com 
Call Date & Time: Tue, 18 Jun 2013 14:40:38 
Branch Info: Rajouri Garden 
City: Delhi

试试这个，您可以从文件中获取输入

public class Test {
public static void main(String[] args) {
    String data = " Lead Details\n" +
            "Caller Name: Mr Rahul from Rajouri Garden\n" +
            "Caller Requirement: Money Exchangers\n" +
            "Caller Phone: +918459761134\n" +
            "Caller Email: rchand.rahul@gmail.com\n" +
            "Call Date & Time: Tue, 18 Jun 2013 14:40:38\n" +
            "Branch Info: Rajouri Garden\n" +
            "City: Delhi";

    String[] subStr=data.split("\n");

    for (String i:subStr){
        if(i.contains("Caller Name")){
            System.out.println("Caller Name: "+i.split(":")[1]);
        }if(i.contains("Caller Requirement")){
            System.out.println("Caller Requirement: "+i.split(":")[1]);
        }if(i.contains("Caller Phone")){
            System.out.println("Caller Phone: "+i.split(":")[1]);
        }if(i.contains("Caller Email")){
            System.out.println("Caller Email: "+i.split(":")[1]);
        }if(i.contains("Call Date & Time")){
            System.out.println("Call Date & Time: "+i.split(":")[1]);
        }if(i.contains("Branch Info")){
            System.out.println("Branch Info: "+i.split(":")[1]);
        }if(i.contains("City")){
            System.out.println("City: "+i.split(":")[1]);
        }
    }
}

}

拆分在这里是一个更好的选择。这是有用的ruchira，但是我是否应该放弃使用regex来实现这个目的
